Neighbor Randy Patton said he saw Trias come out of the house when police took him into custody.

"I saw him in a cop car across the street in the back handcuffed. It looked like he was getting oxygen, like he had a medical issue," Patton said.

Trias had scratches on his face, but police would not say if that is how they found him.

Neighbor Mo Kasham said Trias and his wife, who moved into the home in 1999, did not cause any problems.

"Good neighbors, kept to themselves. No problems. Never had police there before," Kasham said.

Trias had served as coordinator of mathematics tutoring and testing at Eastern Michigan University. The school said that job ended two years ago. He was also a part time lecturer as recently as last month, but was not teaching this semester.
